GM expands market for hydrogen fuel cells beyond vehicles

General Motors is finding new markets for its hydrogen fuel cell systems, announcing that it will work with another company to build mobile electricity generators, electric vehicle charging stations and power generators for military camps…

GM is not alone in entering the hydrogen generator market. Multiple companies, including AFC Energy in the United Kingdom, are selling or testing the products, said Shawn Litster, a professor of mechanical engineering at Carnegie Mellon University who has studied hydrogen fuel cells for about two decades.

There will be more demand for the generators as vehicles switch from internal combustion to electric power. Police departments and municipal governments, he said, will need backup power to charge emergency vehicles in case of a power outage. Hydrogen can be stored for long periods and used in emergency cases, he said.
